If you’ve been looking for some pure delight after a week of heavy news headlines, you may get your chance this weekend. There’s a potential one of nature’s most enchanting shows, the aurora borealis, may be seen across a large swath of the northern United States this weekend.
And, good news for people as far south as Iowa and central Illinois: The northern lights are expected to dip farther south than usual this time around, the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center says.
And, the agency said, under ideal circumstances, people in Missouri, Tennessee, and latitudinal points east and west could get a peek, too.
The agency said geomagnetic activity was expected to rise Friday, Sept. 27, and likely reach moderate storm levels on Saturday, the 28th. The colorful, dancing lights could also be visible early Sunday morning.
The Space Weather Prediction Center will continue to update its forecast through the weekend.
The science behind the northern lights is a bit complicated — all you really need to know is that they are jaw-dropping beautiful. Basically, they become visible to the human eyes when electrons from solar storms collide with the upper reaches of the Earth’s atmosphere.
In normal circumstances, the Earth’s magnetic field guides the electrons in such a way that the aurora forms two ovals approximately centered at the magnetic poles. But during geomagnetic storms, the ovals expand away from the poles and give some lucky people in the United States a sky show they’ll never forget.
Most often, the auroras appear as tall rays that look like a colorful curtain made of folds of cloth, according to the Space Weather Prediction Center.
